最近,我国对“七五”期间低合金用钢科技攻关课题召开了论证会。结果确定13个专项课题列为“七五”低合金钢科技攻关项目,上报国家科委审批。其中,与压力容器有关的有3项,现简介如下: 1.镍系低温用钢的研制专项课题本课题由太钢、鞍钢、北京钢研院和通用所等单位承担,主要针对城市煤加压气化、年产三十万吨乙烯等工程中低温压力容器设备国产化的需要,开展1.5Ni、3.5Ni钢及球罐用低温高强度钢的研制。同时,也对5Ni、9Ni钢开
Recently, China held a demonstration meeting on the subject of low alloy steel technology during the “Seventh Five-Year” period. The results identified 13 special topics as “Seventh Five-Year” low-alloy steel scientific and technological projects, submitted to the approval of the State Science and Technology Commission. Among them, there are 3 items related to pressure vessels, and the brief introduction is as follows: 1. Development of special nickel-based cryogenic steel This project is undertaken by TISCO, Anshan Iron and Steel, Beijing Institute of Steel Research and General Motors and other units, mainly for urban coal plus Pressure gasification, with an annual output of 300,000 tons of ethylene and other low-temperature pressure vessel equipment in the domestic needs of the development of 1.5Ni, 3.5Ni steel and spherical tank with low-temperature high-strength steel research and development. At the same time, also open to 5Ni, 9Ni steel
